public interface IdentifierGenerator

The general contract between a class that generates unique identifiers and the Session. It is not intended that this interface ever be exposed to the application. It is intended that users implement this interface to provide custom identifier generation strategies.

Implementors should provide a public default constructor.

Implementations that accept configuration parameters should also implement Configurable.
Implementors must be threadsafe
